WEED RESISTANCE HAS been slow coming to north Alabama, providing an advantage for growers attempting to battle it, says Auburn University Extension Agronomist Charles Burmester, left, shown here with 2014 High Cotton Award winner Danny Darnell.
There are certain advantages to being last in line, especially if you’re waiting for something like weed resistance.
“We’ve been fortunate in Alabama that glyphosate-resistant weeds didn’t show up quite as early as in other states,” says Charlie Burmester, Auburn University Extension agronomist. “Resistance really hasn’t spread as quickly as it has in other states, and that’s good for our growers.”
Since resistance did occur later in Alabama than elsewhere, the state’s producers learned from what other growers did or did not do, he says.
“For some growers in other parts of the Southeast, it got away from them at the start, and if you let these resistant weeds get away from you, you can never catch up. You have to catch them on the front end, and a lot of our farmers were able to do that. We’ve slowed down the spread of resistant weeds in Alabama, but they are still slowly spreading and we have some hot spots that are severe. They are getting a little worse each year,” said Burmester.
Another resistance problem rearing its ugly head in north Alabama’s Tennessee Valley is horseweed, he adds. Horseweed started showing resistant to glyphosate in the region about 2001 or 2002, he says.
